This dissertation focuses on the formulation and analysis of various fitted numerical methods for
the solution of singularly perturbed parabolic diffusion-type problems characterized by boundary
layers, both in the ...
This Design-Based Research (DBR) study investigated the adaptation of Realistic Mathematics
Education (RME) for teaching Grade 9 mathematics in an Ethiopian secondary school context.
The study addressed the adaptation ...
Despite the recognized importance of productive struggle (PS) in fostering conceptual
understanding in mathematics, a persistent gap exists between its theoretical endorsement and
classroom implementation. In Ethiopia, ...
This study designed, implemented, and examined the effectiveness of technology-integrated
concept-mapping instruction in promoting conceptual understanding and retention of cell-cycle
concepts among Grade 10 biology ...
Biology education, as a part of science education in Ethiopia, continues to face persistent
challenges characterized by low student achievement, limited classroom engagement, and
unfavorable attitudes toward the subject. ...
The purpose of this dissertation is to study the strong minimum/maximum
principle and to investigate various Liouville-type theorems for partial trace equa
tions with nonlinear gradient terms. To investigate the problems ...
Fuzzy set theory provides a mathematical framework for handling uncertainty and partial truth, ex
